The sound level, $\beta$, in decibels (dB), of a sound with an intensity of $I$ is calculated in relation to the threshold of human hearing, $I_0$, by this equation:
$\beta = 10 \log \left(\frac{I}{I_0}\right)$
The threshold of human hearing is $10^{-12}\text{ watts/meter}^2$.
The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately ____ watts/meter$^2$.
$\beta = 10 \log \left(\frac{I}{I_0}\right)$
The threshold of human hearing is $10^{-12}\text{ watts/meter}^2$.
The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately ____ watts/meter$^2$.
